' OHIO, A CORPORATION or DELAWARE VISIBILITY PROMOTION Application led February 4, 1929. Serial No. 337,490.

This invention relates to visibility promoting devices.

VThis invention has utility when incorporated in rounded cone elements. Referring-to the drawings Fig. 1 is a view of an embodiment of the invention in a sign, parts being broken away; Fig. 2 is a vdetail view on an enlarged scale of one of the elements as assembled to promote visibility in the sign of Fig. 1;

Fig. 3 is a section on the line III-III, Fig. 2;

Fig. 4 is a view of further visibility promotion uses of the elements and instead of being in a sign as in Fig. 1, being about a headlight and in the radiator cap, the former to supplement visibility between approaching cars, and the latter to increase visibility range of car driver, more particularly as under traic lights;

Fig. 5 is a detail view of the element; and' Fig. 6 is a section on the line VI-VL Fig.

5, looking in the direction of the arrow.

General support or frame 1 is shown as having letter outline members 2 providing mounting seats in which are mounted rounded cone elements 3 retained in assembly position by nuts 4. Conveniently in practice, sockets5, of a type say for mounting incandescent light bulbs, may carry plugs 6 having terminal threaded portions 7 to be engaged by the nut 4. This plug 6 is additionally provided with concave seat 8 so that as nut 4 is brought into position, its overhang 9 may coact with taper portion 10 of the element 3 in.

the region of cylindrical portion' 11 remote from rounded top or outer terminus 12 of' this element 3. This element 3 on the side of the cylindrical portion 11 remote from the ycaution signal color as amber, red, or green,

contrasting colors, lustrous for promoting reflection, say of an enamel, colored varnish, or Duco character. This parti-colored scheme may be with region 15, yellow; region 16, green; region 17, purple.

These parti-colored elements while of attention-drawing attractiveness for signs or other visibility promoting devices, may have, instead of a contrasting color, a traflic or A when the elements 3 are assembled in ring 18 of motor vehicle headlight for motor vehicle 19. 1n this assembly, the elements in one headlight may be red and in the. other green, or each may be either of these colors or amber according to the fancy of the driver or in conformity with traiiic regulations.

For the convenience of the driver of the vehicle 19, radiator cap 20 may have element 3 therein. This element 3 with its reflector coating 14 on its base and the element 3A of glass, serves as a vision range promoting device or the driver of the vehicle, especially of value where luminous stop signals or trafic regulation devices are installed.

With the closed car type of motor vehicle andthe vision of the driver upward restricted, this radiator cap carried element 3 discloses to the driver the flash change of red to amber or green, or vice versa, so that from the normal driving view position; the operator may check on the condition of the signal for being taken into accountin his driving of the vehicle.

This assembly may be used in some practices in lieu of or to displace electric incandescentlight bulbs.

, What is claimed and it is desired to secure by Letters Patent is: p

1. A double convex visibility promoting device comprising a rounded cone reiection element, a plug support element embracing fitting therefor providing a seat, and a complementary fitting with which said support iitting may be detachably engaged for mounting the element.

2. A visibility promoting device compris- -ing a rounded cone reflection element having a. dare base portion, a plug support having a seat for the base, and a plug engaging nut 1T for engaging the hase, said nut having an overhang for detachably assembling the element with the plug in thereby anchoring the element in seat-engaging position with the plug.

3. A visibility promoting device comprising a rounded cone reflection element having a, flare base portion, and an externally threaded plug support having a seat therein for the base, said seat having means overhanging the Hare portion in thereby anchoring the element with the support.

In witness whereof I ailix my si DAVID C. S
